Network Services Checker (NSC) is a tool for sysadmins to check status of services on server.
It tries to connect to services as configured, and reports if connection has been estabilished or not.
NSCs main purpose is to give a global and fast report of network status.
Enhancements:
- fixed some non-standard javascript functions
- fixed a bug editing server parameters
- some other little improvements and bugfixes

The Simple RSS Service (SRSSS) generates and serves RSS feeds through a common interface via CGI-enabled webservers. It uses modules to extract items for feeds from various sources, and has a virtual filesystem where feeds can be read by CGI-clients.
The package contains everything needed to start providing RSS feeds, including server and CGI programs, and has support for PostgreSQL, MySQL and MimerSQL.
Main features:
- Modular and clean design based on object oriented C++
- Resource-friendly functions that keeps the load down on web- and database-servers by only parsing data and generate new feeds when required, instead of at every request.
- Interface for run-time loading of modules for data-extraction
- A virtual filesystem stored in shared memory
- Feed extraction via CGI program for easy integration in any CGI-enabled webserver
- A trigger-system that allows external sources to trigger daemon software to fetch new updates
- Easy configuration via a configfiles
- Designed for easy integration towards SQL servers etc
- Support for NetBSD, FreeBSD, OpenBSD and Linux.
Modules:
These modules are currently available for RSS item extraction:
mod_pgsql
This module allows the RSS daemon (rssd) to extract items for RSS feeds from a PostgreSQL database. It can select an entire column as description field for the feed, or base it on a pre-formated string in which variables are replaced with values from columns returned in the SQL query.
This module also support triggering, where any client connected to the same database is able to trigger RSSD to fetch a new update via the SQL LISTEN and NOTIFY functions.
mod_mysql
This module integrates RSSD with the MySQL database, allowing it to produce RSS feeds based on any information stored in databases running on MySQL. The module allows the user to run just about any SQL query supported by the database to extract the needed information to create a feed.
Mod_mysql does also support pre-formated strings to generate the description for each RSS item it produces.
mod_mimersql
This module allows the RSS daemon to fetch items from the MimerSQL database.
The module allows the user to run just about any SQL query supported by the database to extract the needed information to create a feed.
Mod_mimersql does also support pre-formated strings to generate the description for each RSS item it produces.
mod_template
This is a template-module that can be used as a starting-point when developing new modules. It is usable, but does not really provide a usable feature.

The QDS library allows Qt applications to access features provided in common desktop APIs in a portable way, without requiring dependencies on any desktop platform library.
This is especially useful for applications targeting the Unix desktops, because Qt/X11 is very generic and only provides features it can implement on all sub platforms. All library code is licenced under 2-clause BSD licence.
Service implementations are loaded from plugins which link to the respective desktop libraries. The plugin to use can be specified on the applications commandline, in the QDS configuration file or QDS can try to autodetect the currently running platform.
Enhancements:
- Autodetection to use GNOME plugin in case GNOME_DESKTOP_SESSION_ID is set
- Replaced the primitive example application with a simple but network aware text editor application
- Support for wildcards in mailcap entries

Service Control is a basically it allows you to easily control services. Very very simple.

Currently only for Gentoos service directories, so if you use another distrobution, youll have to edit the initial combo variable to suit your needs.

NEEDS TO BE RUN AS ROOT!

Installation:

The simplest way to compile this package is:

1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.

Running `configure takes a while. While running, it prints some messages telling which features it is checking for.

2. Type `make to compile the package.

3. Type `make install to install the programs and any data files and documentation.

4. You can remove the program binaries and object files from the source code directory by typing `make clean.

Recon is an SSL audit tool, checking for common, certificate-related errors in SSL-enabled services. Provide it a list of SSL services for which you are responsible, it runs them periodically, a Recon will warn you of impending certificate expirations, mismatched certificate names or unavailable services.
